METSO D200137: Profibus DP Fieldbus Interface Module
The METSO D200137 is a dedicated Profibus DP communication module engineered for the Metso DNA (Valmet DNA) automation platform. It serves as a gateway between the DCS controller and Profibus DP field devices, supporting both master and slave configurations. The module integrates a high-speed Profibus interface with galvanic isolation, baud rates up to 12 Mbps, and support for up to 125 slaves. Redundant communication ports ensure uninterrupted operation in critical processes. It is fully configurable via the system engineering tool and includes comprehensive diagnostic functions. The D200137 is used in industries such as power, pulp and paper, chemical, and oil and gas for integrating intelligent field devices into the control system.
System Integration
The D200137 is designed for direct integration into Metso DNA I/O racks, occupying a single slot and communicating with the system controller over the backplane. It supports both Profibus DP master mode for controlling field devices and slave mode for connection to higher-level Profibus networks, providing maximum flexibility in system architecture.
Key Features and Functional Capabilities
Dual Redundant Profibus Interfaces: Two independent Profibus DP ports support ring or line redundancy, ensuring continuous communication even in the event of a cable break or interface failure.
High-Speed Communication: Supports baud rates from 9.6 kbps up to 12 Mbps, with automatic detection and configuration for optimal network performance.
Large Device Capacity: Capable of addressing up to 125 Profibus DP slaves per module, suitable for large-scale automation networks.
Galvanic Isolation: All field-side connections are galvanically isolated to 1500V AC, protecting the control system from ground loops and electrical transients.
Flexible Operating Modes: Configurable as Profibus DP master (Class 1) or DP slave, with support for DP-V0, DP-V1, and DP-V2 extensions for advanced diagnostics and isochronous operation.
Comprehensive Diagnostics: Front-panel LEDs indicate module status, communication activity, and fault conditions. Detailed diagnostic data is accessible via the system engineering tool, including bus statistics and device status.
Hot-Swap Support: Modules can be replaced while the system is powered, minimizing downtime during maintenance or network expansion.
Robust Environmental Design: Conformal-coated PCB protects against humidity, dust, and corrosive gases. Operating temperature range -20°C to +60°C, storage -40°C to +85°C.
